Problems solved by technology

[0003] At present, there are mainly the following hidden dangers in the switching operation: First, the operation and maintenance personnel fill in and review the operation ticket when the workload is heavy and the actual situation on the site is unclear.
Second, due to insufficient operating light, poor mental state of personnel, etc., frequent accidents occurred due to accidental entry into the interval and improper operation
Third, the operation and maintenance team often forgets to upload relevant operations and record photos, which makes it difficult to advance safety management and control work

Embodiment 1

[0045] see figure 1 , a substation switching operation management method based on image processing, comprising the following steps:

[0046] Scan and identify the operation ticket, obtain the image of the operation ticket and the switching operation content recorded in the operation ticket, including the work content and operation sequence of each switching operation step;

[0047] Set up monitoring equipment near each power equipment to obtain video images of operators operating each power equipment;

[0048] Identify the image of the operator operating each power equipment, and obtain the operator's operation content and operation sequence;

[0049] Compare the operation content and operation sequence of the operator with the switching operation content recorded in the operation ticket, confirm whether the operator, operation content and operation sequence are the same as the switching operation content on the operation ticket, and mark the comparison on the operation ticke...

Embodiment 2

[0052] This embodiment not only has the beneficial effects of Embodiment 1, but also proposes to scan and identify the operation ticket, obtain the image of the operation ticket and the switching operation content recorded in the operation ticket, including the work content and operation sequence of each switching operation step The specific method and the specific method of identifying the image of the operator operating each power equipment, and obtaining the operation content and operation sequence of the operator;

[0053] Further, see figure 2 Obtaining the image of the operation ticket by OCR technology, matching the image of the operation ticket with the preset operation ticket template, and then performing the image segmentation step;

[0054] The bill segmentation step is as follows: the operation ticket image is mapped to a preset operation ticket template, and the operation ticket template is preset with a cutting area of ​​switching operation content (such as fi...

Embodiment 3

[0065] see figure 1 , a substation switching operation management system based on image processing, including a memory and a processor, the memory stores instructions, and the instructions are adapted to be loaded by the processor and perform the following steps:

[0066] Scan and identify the operation ticket, obtain the image of the operation ticket and the switching operation content recorded in the operation ticket, including the work content and operation sequence of each switching operation step;

[0067] Set up monitoring equipment near each power equipment to obtain video images of operators operating each power equipment;

[0068] Identify the image of the operator operating each power equipment, and obtain the operator's operation content and operation sequence;

[0069] Compare the operation content and operation sequence of the operator with the switching operation content recorded in the operation ticket, confirm whether the operator, operation content and operat...

Abstract

The invention relates to a transformer substation switching operation management method and system based on image processing, and the method comprises the following steps: scanning and recognizing anoperation ticket, and obtaining the image of the operation ticket and the switching operation content recorded by the operation ticket, wherein the switching operaiton content includes the work content and operation time sequence of each switching operation step; arranging monitoring equipment near each piece of power equipment, and acquiring video images of operating personnel for operating eachpiece of power equipment; identifying the images of each piece of power device operated by an operator, and obtaining the operation content and the operation time sequence of the operator; and comparing the operation content and the operation time sequence of the operator with the switching operation content recorded by the operation ticket, determining whether the operator, the operation contentand the operation time sequence are the same as the switching operation content on the operation ticket or not, marking a comparison result on the operation ticket, and returning the operation ticketafter marking is completed.

Description

technical field [0001] The invention relates to a switching operation management method and system based on image processing, belonging to the technical field of power systems. Background technique [0002] Electrical equipment is divided into three states: operation, standby (cold standby and hot standby), and maintenance. The process of changing the equipment from one state to another is called switching, and the operation is called switching operation. By operating isolating switches, circuit breakers, and hooking and disconnecting grounding wires, electrical equipment can be converted from one state to another or the system can change its operating mode. This operation is called switching operation. The switching operation must implement the operation ticket system and work guardianship system. [0003] At present, there are mainly the following hidden dangers in the switching operation: First, the operation and maintenance personnel fill in and review the operation t...
